Monolayer tungsten disulfide (ML WS2) is believed as an ideal photosensitive material due to its small direct bandgap, large exciton/trion binding energy, high carrier mobility, and considerable quantum conversion efficiency. Compared with other photosensitive devices, planar field emission (FE)‐type photodetectors with a full‐plane structure should simultaneously have rapider switching speed and...
Electrochemical CO2‐to‐CO conversion offers an attractive and efficient route to recycle CO2 greenhouse gas. Molecular catalysts, like CoPc, are proved to be possible replacement for precious metal‐based catalysts. These molecules, a combination of metal center and organic ligand molecule, may evolve into single atom structure for enhanced performance; besides, the manipulation of molecules’ behavior...
Wearable glucose sensors are of great significance and highly required in mobile health monitoring and management but suffering from limited long‐term stability and wearable adaptability. Here a simultaneous component and structure engineering strategy is presented, which involves Pt with abundant Ni to achieve three‐dimensional, dual‐structural Pt‐Ni hydrogels with interconnected networks of PtNi...
High‐valence metal‐doped multimetal (oxy)hydroxides outperform noble metal electrocatalysts for the oxygen evolution reaction (OER) owing to the modified energetics between 3d metals and high‐valence dopants. However, the rational design of sufficient and subtle modulators is still challenging. With a multimetal layered double hydroxide (LDH) as the OER catalyst, this study introduces a series of...
The shuttle effect of soluble lithium polysulfides (LiPSs) leads to the rapid decay of sulfur cathode, severely hindering the practical applications of lithium‐sulfur (Li‐S) batteries. To this point, a covalent‐organic framework (COF) with proper cationic sites, which can be utilized as the cathode host of high‐performance Li–S batteries, is reported. The chemical sulfur anchoring within micropores...
To address demands for increased data transmission rates, electrically small antennas (ESAs) that simultaneously offer large frequency bandwidths and small physical sizes are of growing interest. 3D layouts are particularly important in this context and among various 3D ESAs, systems that adopt hemispherical shapes are very promising, because they can occupy the entire Chu‐sphere and offer outstanding...
Combining luminescent transition metal complex with super‐resolution microscopy is an excellent strategy for the long‐term visualization of the dynamics of subcellular structures in living cells. However, it remains unclear whether iridium(III) complexes are applicable for a particular type of super‐resolution technique, structured illumination microscopy (SIM), to image subcellular structures. Herein,...
Boron is a narrow‐bandgap (1.56 eV) semiconductor with high melting‐point, low‐density, large Young's modulus and very high refractive index (3.03) close to silicon. Therefore, boron nanostructures is expected to possess strong visible‐light scattering properties. However, photonic and optoelectronic properties of the boron nanostructures are seldom studied until now. In this paper, we have successfully...
Near‐infrared (NIR) laser‐controlled gene delivery presents some benefits in gene therapy, inducing enhanced gene transfection efficiency. In this study, a “photothermal transfection” agent is obtained by wrapping poly(ethylenimine)‐cholesterol derivatives (PEI‐Chol) around single‐walled carbon nanotubes (SWNTs). The PEI‐Chol modified SWNTs (PCS) are effective in compressing DNA molecules and protecting...
